Volt Could Receive 100 MPG Rating From EPA

Problem revolves around how to measure the vehicle's fuel economy when the engine may run only 15% of the time.

General Motors Corp. has reached agreement with the California Air Resources Board that could result in the Chevrolet Volt range-extended electric vehicle receiving a 100 mpg fuel economy rating from the EPA, the company said.

GM spokesman Dee Allen said the rating is far from set, stressing that what has been agreed to on a preliminary basis is that the Volt would be classified as an extended-range electric vehicle for the purpose of fuel-economy ratings.

If that is made certain, he said, then the Volt, due out in November 2010, could would likely receive a rating of 100 miles per gallon or better.


Powered by advanced lithium-ion batteries and two 67bhp (50kW) electric motors to drive the front and rear axles, the Mixim is a four-wheel-drive car with a theoretical top speed of 112mph and a potential maximum range of 156 miles.

Dodge ZEO is 2+2 electric muscle car for the 21st century powered by 200kW electric drive with 0-60 mph in less than 6 seconds and range of 250 miles.

The Air Car may do better than fuel-cell cars, but experts say that using grid power to charge a battery-powered electric vehicle is much more efficient than using electricity to compress and store the same amount of energy in a tank.
